ILOUG 2019 - Flashback, the forgotten featureConnor McDonald
Slides from the ILOUG 2019 conference. There is a remarkable human condition where you can be both cold AND sweaty at the same time. It comes about 3 seconds after you press the Commit button and you realise that you probably needed to have a WHERE clause on that "delete all rows from the SALES table" SQL statement. Or it might come just after you run "drop table" on the Production database, when you were just so sure that you were logged onto the Test system. This session will discuss how you can use the FLASHBACK features to overcome this uniquely human condition
OG Yatra - Flashback, not just for developersConnor McDonald
Flashback is not only for those "Oh No!" moments when we make a mistake. It enables benefits for developers ranging from data consistency to continuous integration and data auditing. Tucked away in Enterprise Edition are six independent and powerful technologies that might just save your career—they will also open up a myriad of other benefits of well.

Cassandra as the heart and soul of a Lambda Architecture for realtime data analysis. Based on work with Apache Storm, Spark Streaming, Spark and DataStax Cassandra.
This will walk you through the installation of a Cassandra (1.2) node on an Ubuntu (12.04) server.
It will teach you to configure LVM, XFS, /var/lib/cassandra/data and /var/lib/cassandra/commitlog directories.
It will also teach you how to install OpsCenter (FREE) from Datastax to help manage it all.
This was based on a talk given at the Toronto Cassandra Meetup on August 7th, 2013 by myself, Victor Anjos.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
